The role of iodide salts on beef and chicken patties lipid oxidation

In Brazil it’s a legal practice to add iodide to salt. Lipid oxidation is a problem to the quality of meat products. NaCl added to this products acts as a catalyst in lipid oxidation. It has been associated to increasing of TBARS index and also to meat discoloration because of metals contamination. We studied the lipid stability in patties prepared with salt with or without iodide, and mixed with meat from chicken or beef. Ground meat was mixed and ice, salt, onion, garlic and white powder pepper were added, shaped, packaged and stored in freezer. Lipid oxidation was monitored by TBARS (distillation method), in frozen samples and iodide was quantitatively measured throughout 90 days of experiment. The content of lipids in beef samples was 73,31% higher than for chickens one. On the other hand lipid oxidation was higher (56,40% more) in chicken samples. Iodide presence (14,41%) did not affected lipid oxidation, in both meat as would be expected for an oxidant halogen salts.
